What is a chain of underwater mountains along which seafloor spreading occurs?
What is a chain of underwater mountains along which seafloor spreading occurs?
A chain of underwater mountains along which sea-floor spreading occurs is a Mid ocean Ridge.
What is the underwater chain called?
Undersea mountain ranges are mountain ranges that are mostly or entirely underwater, and specifically under the surface of an ocean. If originated from current tectonic forces, they are often referred to as a mid-ocean ridge. In contrast, if formed by past above-water volcanism, they are known as a seamount chain.
What is seafloor spreading called?
The phenomenon is known today as plate tectonics. In locations where two plates move apart, at mid-ocean ridges, new seafloor is continually formed during seafloor spreading.
What is an underwater mountain system called?
A seamount is an underwater mountain. A rise is an underwater mountain range located where tectonic plates are spreading apart. A rise is also known as a mid-ocean ridge.
What is sea-floor spreading and what causes it?
Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle’s convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor.
Who discovered seafloor spreading?
Harry Hess
Harry Hess: One of the Discoverers of Seafloor Spreading.
What is a raised ridge called?
Magma then oozes up from the mantle to fill in the space between the plates, forming a raised ridge called a mid-ocean ridge.
Are there underwater mountains?
Underwater mountains are known as seamounts and are extinct volcanoes rising hundreds to thousands of meters above the seafloor. While active, these volcanoes create large piles of lava that make up underwater mountains.
What is the answer of a long narrow chain of underwater hills or mountains?
ridge
A ridge is a long, narrow chain of hills or mountains. The Mid-Atlantic Ridge is now known to be part of an underwater mountain chain that winds 65,000 kilometers around the earth. The underwater ridges throughout the world vary greatly in size and shape.
What is the name of the longest mountain chain on Earth?
The longest mountain range on Earth is called the mid-ocean ridge. Spanning 40,389 miles around the globe, it’s truly a global landmark.
